摘要:
Provided are a device for producing a disposable wearable article and a method for producing a disposable wearable article capable of suppressing the occurrence of a sealing failure by making it difficult for a doubled sheet to open against an elastic force of an absorber. A device for producing a disposable wearable article includes a jointing/cutting unit (60) provided in a line (LI) for continuously conveying a sheet (W) and configured to join parts of the doubled sheet (W) at opposite sides of an absorber (C) and then cut the joined parts and a pressing unit (70) arranged upstream of the jointing/cutting unit (60) in a conveying direction (a). The pressing unit (70) includes a pressing mechanism (71, 72) configured to press the sheet (W) together with the absorber (C) in a thickness direction.
摘要:
A method for producing an absorbent structure intended for use in an absorbent article, such as a sanitary napkin, incontinence guard, diaper, wherein the absorbent structure in produced by laying a layer of essentially superabsorbent material between two layers of defibered and moisturized cellulose pulp or tissue, whereafter the composite structure is calendared between one or more pairs of heated rolls, wherewith the layer of superabsorbent material binds in itself and forms a stable layer, which binds to the surrounding cellulose pulp layers or tissue layers. The absorbent structure exhibits excellent absorption properties and can be made very thin. The structure can be manufactured without superabsorbent material being spread around the manufacturing machine during the production process, or escaping from the finished absorbent article when packaging, transporting or using the article.

摘要:
A method for mechanically deforming, such as by bonding, a substrate assembly. The substrate assembly may be advanced at first velocity toward a bonder apparatus. The bonder apparatus may rotate at a second velocity, which is less than or equal to the first velocity. The bonder apparatus may include a support surface and a process assembly. The substrate assembly may be contracted prior to advancing onto the bonder apparatus. A first process assembly may receive a leading portion of the substrate assembly and a subsequent process assembly may receive a trailing portion. The leading portion and the trailing portion define a product arc length, which is less than or equal to a process product pitch. One or more processes may be performed on the substrate assembly. The substrate assembly may then be removed from the apparatus and advanced through a metering assembly such that the substrate assembly exits at the first velocity and may be expanded such that the leading portion and the trailing portion are separated by the process product pitch.
摘要:
One surface of a belt-shaped sheet laminate (10) (continuous diaper strip), in which a plurality of sheets are laminated, is made to abut against a support member (21) having a light passage section (27) through which a laser beam (30) can pass, and the belt-shaped sheet laminate (10) which is in a pressurized state is irradiated, from the support member (21) side via the light passage section (27), with a laser beam (30) having a wavelength that is absorbed by the sheets constituting the sheet laminate (10) and that causes the sheets to generate heat, and thus, the belt-shaped sheet laminate (10) is cut and separated and, simultaneously, cut edge sections created, by the cutting/separation, in the plurality of sheets which are in the pressurized state are fusion-bonded together. Thus, sealed edge sections (4) (side seal sections) are formed by fusion-bonding the edge sections of the plurality of sheets in a state where the sheets' edge sections are superposed.
摘要:
An absorbent article may comprise a chassis having a front waist region, a rear waist region, a crotch region between the front waist region and the rear waist region, a pair of longitudinal edges, and a pair of side panels extending between and connecting the front waist region and the rear waist region to form a leg opening. Each side panel may comprise a uniformly colored stretch laminate. The stretch laminate may comprise a colored elastomeric member and a first substrate joined to the elastomeric material. The side panels may be joined by a mechanical bond which may form an informational indicia.
摘要:
A method for making an edge fold on an absorbent article having longitudinal edges including the steps of activating a portion of an absorbent article along its longitudinal edges to create substantially uniform gathers, folding a portion of the absorbent article along its longitudinal edges, and bonding a portion of the absorbent article along its longitudinal edges. Said method may include the step of cutting a portion of the absorbent article before the step of folding. Said method may include the step of cutting a portion of the absorbent article after the step of bonding. Said step of activation may include the application of heat to the absorbent article to assist in the activating process, whether before or during activation. Said bonding may be performed by application of adhesive, ultrasonic bonding, compression bonding, thermal bonding, radio frequency bonding, infrared bonding and combinations thereof. Absorbent articles include disposable diapers, sanitary napkins, pantiliners, incontinence briefs, and incontinence undergarments. Said step of folding creates an edge fold that substantially covers a portion of a longitudinal edge between a pair of side panels.
